Definitions

  • the present invention relates to a tape having a series of pockets along its length for storage of electronic components see e.g. GB-A-2 163 401.
  • An electronic flatpack is a relatively thin package containing numerous electronic components and which is rectilinear in shape (being either square of rectangular) provided on all four side faces with proprotruding, cranked or gull wing, connector pins, which are generally made of fine closely spaced wires for connection of the components to a printed circuit.
  • the connector pins are numerous to convey signals to and from the numerous components contained within the flatpack and as the packing density of these components increases so the gauge of the pins and the spacing of the pins decreases so that in flatpacks which are currently available the pins are filigree in nature and highly vulnerable to damage or distortion prior to being secured to the printed circuit.
  • Removal of the flatpack from the tray recess is often an automatic process in which a pick-up device such as a suction nozzle is placed in contact with and lifts the flatpack. Often, however, the lift is not vertical and the protruding cranked connector pins are deformed or broken off due to contact with the walls or floor of the recess making the flatpack difficult or impossible to fit to the printed circuit, or inoperative.
  • a pick-up device such as a suction nozzle
  • an electronic parts carrier comprising a reel on which is wound a tape having a series of pockets along its length which have been depressed out of the original plane of the tape and whose openings lie in the original plane of the tape, the tape being made of a semi-rigid plastics material so that the tape portions separating adjacent pockets are capable of providing a hinge function whereby the tape can be would on the storage reel without distortions of the individual pockets, each pocket comprising a floor and walls, the floor being disposed at a predetermined depth (W) from the original plane of the tape, the series of pockets being spaced inwardly from the edges of the tape to define outer marginal edge portions on the tape, wherein along each tape marginal edge portion there is provided a row of sprocket holes and, inwardly of said holes a length of cover film is releasably secured to a continuous tape surface by two longitudinally extending lines of adhesive so that the cover film extends along the length of the tape over the series of pockets, and a portion of the
  • said pocket is square in outline and said protrusion has four separated portions respectively aligned with the walls of the said pocket.
  • the tape is provided with about 250 pockets along its length.
  • an electronic flatpack having protruding cranked connector pins is stored in a pocket disposed on a tape and is carried by a support surface formed by inward deformation of a portion of said pocket floor, said support surface facilitating removal of said flatpack using a suction nozzle with minimal contact between said connector pins and the walls of said pocket.
  • a tape 10 in accordance with the present invention comprises a series of pockets 12 along its length, only one of which is shown in the interests of clarity.
  • the tape is made of semi-rig id plastics material and the pockets, which are square in outline, are separated from one another along the length of the tape by tape portions 13 which are bendable so as to function as hinge like portions.
  • the pockets 12 by virtue of being pressed or moulded out ofthe original plane 8 of the tape are relatively rigid.
  • Each pocket 12 has walls 16 and a pocket floor 12A, at a depth W from the original plane 8 of the tape, (shown in Fig. 2), which is inwardly deformed to define a protrusion 14 around the pocket floor 12A with portions in alignment with the pocket walls 16.
  • the protrusion 14 is itself profiled to define a support surface 14A (which also extends generally rectilinearly) disposed at a first clearance X from the pocket floor 12A and a ridge 14B which extends along the outer peripheral boundary of the support surface 14A, being offset from the longitudinal centre line of the support surface 14A towards the pocket walls 16.
  • the top of the ridge 14B is disposed at a second clearance Y from the pocket floor 12A and is spaced by a third dearance Z from the walls 16 of the pocket.
  • the protrusion 14 shown in Fig. 1 is formed by four separated portions 14C, 14D, 14E, 14F which are respectively aligned with the walls 16 of the pocket 12. It will, however be appreciated that the protrusion 14 could be unitary and extend in a generally rectilinear fashion around the pocket floor. Also, the pocket and the protrusion may both be ether square or rectangular in outline according to the outline shape of the flatpack 18 which is to be housed. Currently known flatpacks are either square or rectangular in outline.
  • the flatpack 18 has a relatively thin body 19 from which protrude cranked connector pins 20 which are very fragile.
  • the body 19 is of predetermined dimensions and is carried in the pocket 12 by the support surface 14A with the pins 20 disposed over the ridge 14B and projecting into the third dearance Z.
  • the thickness of the body 19 governs the dimension W-X so that the upper surface of the body 19 is essentially aligned with the original plane 8 of the tape 10 and a cover film 21 is releasably secured over the opening into the pocket 12 to hold the flatpack 18 onto the support surface 14A,
  • Film 21 extends along the length of the tape 10 and is secured thereto by only two longitudinally extending lines of adhesive 25 (Fig.1) which respectively lie between a tape edge and a pocket edge. This arrangement facilitates peel back of the film when the tape is in use as will be explained.
  • rows of sprocket holes 23 which permit the tape 10 to be controllably unwound from its storage reel 24A (shown in Fig. 4).
  • the tape is unwound from the reel 24A by a pull-off sprocket 24B which is controllably indexed to present a flatpack 18 at a withdrawal station 26.
  • the cover film 21 is peeled back around rollers 25A and 25B to expose the flatpack at station 26 whereat a suction nozzle 22 is moved to engage and lift the flatpack 18 from the pocket 12 as schematically shown in Fig. 4.
  • the lift is not orthogonal to the floor 12A of the pocket 12 and the flatpack 18 is removed at an angle, because the support surface 14A is disposed from the pocket floor by a clearance X and the ridge 14B is disposed at a clearance Z from the pocket wall 16 and by clearance Y from floor 12A the pins 20A are prevented from coming into contact with the wall 16 or the floor 12A so that damage to the pins 20A is prevented.
  • the tape is indexed forward by sprocket wheel 24B and is engaged by a chopping device 27 which chops the used tape into short lengths for subsequent disposal.
  • the support surface 14A surrounds a hollow to provide strength to the protrusions 14C, 14D, 14E, 14F.
  • the tape is fabricated of a semi-rigid plastics material such as polystyrene or PVC to facilitate winding of the tape onto the reel 24A. Additionally the film covering the pockets on the tape may be transparent to allow inspection of the flatpacks therein.
